A lubrication monitoring device monitors a lubricating condition of a lubricator feeding an oil droplet at a predetermined time interval by means of a discharge nozzle having a nozzle orifice. The lubrication monitoring device comprises: a pair of electrodes disposed in the proximity of the nozzle orifice; a capacitance detecting portion for detecting the variation of capacitance between the pair of electrodes, the capacitance varying in conjunction with the varying amount of oil fed from the nozzle orifice to space between the pair of electrodes; and a determination portion for determining whether the oil droplet is fed at the predetermined time interval or not, the determination made based on the detection result supplied from the capacitance detecting portion.

Minute elements are formed while a photo deviation is suppressed between a spin torque oscillator and a main pole and damage is prevented on the ends of the spin torque oscillator in microwave-assisted recording. A magnetic recording head used for microwave-assisted recording includes: a main pole; a spin torque oscillator that is disposed on the main pole and includes a magnetization high-speed rotation layer for rotating magnetization at a high speed by a spin torque; a protective film that is disposed in the track width direction of the spin torque oscillator; an insulating film formed over the wall surfaces of the main pole and the wall surfaces of the protective film; and a magnetic film formed on the insulating film so as to cover at least the main pole.

A stacked ring 2 that forms a transmission belt is formed by stacking a plurality of elastically deformable ring materials 201 to 206 together. Shot peening is performed on surfaces of the ring materials 201 to 203 of the first layer as the innermost layer to the third layer so that a residual compressive stress in the ring materials 201 to 203 is higher than that in the ring materials 204 to 206 of the fourth to sixth layers. The outer circumferential length of the ring material 203 of the third layer is longer than the inner circumferential length of the ring material 204 of the fourth layer, and the ring material 203 of the third layer is press-fit into the ring material 204 of the fourth layer.

A motor controller controls a motor including a rotor and a stator opposed to the rotor. The motor controller includes an electric current driving unit which drives the motor with an axis electric current value defined in a rotating coordinate system defined with respect to a control angle that is a rotation angle for control, a control angle computing unit which computes a current value of the control angle by adding an addition angle to a previous value of the control angle in each predetermined computing cycle, and an addition angle computing unit which computes the addition angle according to a torque to be generated by the motor or a response of the motor to the axis electric current value.

A method for manufacturing a belt for a continuously variable transmission (CVT) in which multiple V blocks of a plurality of types having different thicknesses are attached to an endless body. The method includes forming a plurality of V block groups respectively having a different ratio of different types of V blocks; and forming a series of V blocks by attaching a plurality of V blocks to the endless belt to provide said plurality of V block groups. The V block groups have different ratios of the plurality of types of V blocks to provide a belt whose noise level is low and dispersed.

The first element has a first thickness. The second element has a second thickness that is smaller than the first thickness, and the number of second elements is approximately equal to that of the first elements. Both the first and second elements are supported by the hoop so as to stack in the thickness direction according to a maximum length sequence.
摘要:
At the time of starting a vehicle, the torque capacity of a friction engagement element is made less than the torque capacity of a continuously variable transmission by setting a ratio between the pressure-receiving area of a control oil chamber (77a) of a garage shift control valve (77) and the pressure-receiving area of a feedback chamber (77d) of the valve, and a ratio between the pressure-receiving area of a control oil chamber (73a) of a secondary sheave control valve 73 and the pressure-receiving area of a feedback chamber 73d of the valve. This allows a control based on a single linear solenoid valve SLT although the control is for eliminating slip of a belt of the continuously variable transmission. Therefore, the construction of the oil pressure control apparatus is simplified so that the size and cost thereof can be reduced.
